In a couple of years you won't even have to do that. You can drive to Vegas on a Tesla (or a Model 3 in two years) from pretty much anywhere in the US, by utilizing the supercharger network: http://supercharge.info/ . And in a couple of years it'll cover all of the major routes.

We are talking about natural gas, not hydrogen. You can burn natural gas in solid oxide cells but so far none exist that are practical (otherwise all those gas turbines would have switched). And the _real_ (not proposed theoretical) numbers are miserable. See here: https://en.wikipedia.org/wiki/... - that's with cogeneration (i.e. waste heat is also reused).

This is nothing more than a window dressing to greenwash increasing dependency of Germany on natural gas.

I've been hearing this since 2000-s and the price for wind did come down. But the cost of offshore generation also is not coming down. There's a reason for this - sea is a hostile environment and turbines have to be built to withstand much more aggressive weather.

The main problem with renewables right now is lack of energy storage, so simply scaling variable sources doesn't work at all. It's looking to be a fundamental problem that can derail the whole transition.

Even in Europe the installed offshore wind capacity is pretty much a rounding error. If we look at Denmark then they have 1.2GW of installed offshore generation with a capacity factor of about 20%. So that's just 300MW of average generation without guaranteed capacity. I.e. less than one block of a modern thermal power plant or 1/4-th of one reactor in a modern nuclear power plant.

It's mostly OK for Denmark because they export excess energy into Norway and Sweden which store it in hydroaccmulating powerplants. But that doesn't scale at all.
